LIGO 2006

The 2006 LIGO workshop will focus on the physics behind the exhibits at LIGO.

We'll work at the exhibits and in a classroom with simple Snack versions of the exhibits.

We'll also investigate some basic scientific inquiry techniques.

This workshop will be based on LIGO we'll do activities derived from each part of the name.

Laser: We'll look at light, its spectrum, mirrors and images, and then at lasers.

Interferometric : We'll look at interference of light and then use the Michelson Interferometer

Gravity : We'll explore gravity and tides at the Gravity Well.

Wave : We'll look at waves in coiled phonecords and at the Giant Slinky.

Observatory : And everything will be based on Inquiry, on seeing and doing.

Introductory activity

Feel Temperature, Everyone will line up according to their hand temperature.

Minimag light explorations.

Locating Rays, Look at the bare bulb of a minimag light, notice the rays of light, where are they?

Afterimage: Stare ahead at a fixed point move the bare-bulb-minimag light around and study the afterimage.

Seeing Your Retina Stare at a black background, move the minimag light around and see the blood supply to your retina.

Shadow Size and Distance, Use the small lightsource of the maglite to study shadow size versus distance.
